I uploaded a patch for this addon.
It adds a few features, such as MSBT/Parrot/SCT redirects and a better config.
It also supports full localization, as far I know.
Its also quite a bit more efficent, but it needs testing.

Until I get a hold of the author Its the only thing I can do to keep this epic addon alive.

Reading the code, it looks like it only does raid/party notifications, so if you're not grouped you only hear the sounds (which is what happened to me in a BG). Would it be possible to add an option to do visual warnings, maybe routing through sct? WitchHunt can probably take care of it, I guess, but since this is a specialized addon like DMBMB, it'd be useful to have "extra" warning
